ChromeOS Custom Policies

Administrators can create custom ChromeOS policies using predefined templates for faster configuration.

Chrome OS Low Battery Sound

  • Enable it to ensure users are alerted before shutdown.
  • Disable it in quiet environments like classrooms, libraries, or testing centers.
  • Replace:
    • {{ORGUNIT}} with Your actual OU ID
    • "UNSET" with TRUE, FALSE, or UNSET
Placeholder Replace With
{{ORGUNIT}} Your OU ID
"UNSET" TRUE, FALSE, or UNSET

Chrome OS Time Zone Template

Configures the device time zone for ChromeOS devices

Placeholder Replace With
{{ORGUNIT}} Your OU ID
"America/Los_Angeles" Valid IANA time zone
timezoneDetectionType Desired detection mode

Chrome OS On Screen Keyboard Template

It controls whether the virtual (on-screen) keyboard is available on the ChromeOS login screen.

Placeholder Replace With
{{ORGUNIT}} Your OU ID
"UNSET" TRUE, FALSE, or UNSET

Chrome OS USB Access Template

This policy controls which USB detachable devices (such as USB storage drives or removable media) are explicitly allowed on managed ChromeOS devices.

Item What To Replace Effect
{{ORGUNIT}} OU ID Applies policy to that OU
[] List of vendorId + productId objects Controls which USB devices are allowed
Empty list No devices allowed (if restricted) -
Specific list Only listed devices allowed -
Note: This policy works together with other USB or external storage restriction policies. If USB access is not restricted elsewhere, the allowlist may not have visible impact.

Chrome OS Scheduled Reboot Template

This policy allows administrators to schedule automatic reboots for managed ChromeOS devices within a specific Organizational Unit (OU).

Field What to Replace Effect
{{ORGUNIT}} OU ID Applies to that OU
deviceScheduledRebootEnabled true / false Turn reboot on/off
hours, minutes Desired 24h time Sets reboot time
deviceScheduledRebootFrequency DAILY / WEEKLY Sets reboot frequency

Chrome OS Screen Setting Template

This policy controls display configuration behavior on managed ChromeOS devices within a specific Organizational Unit (OU).

It allows administrators to:

  • Control whether users can change display settings
  • Force specific external display resolutions
  • Control display scaling
  • Enforce standardized screen configurations
Field What to Replace Effect
{{ORGUNIT}} OU ID Applies to selected OU
allowUserDisplayChanges true / false Allow or lock display changes
externalUseNativeResolution true / false Use monitor default or custom resolution
externalDisplayWidth/Height Pixel values Force custom resolution
externalDisplayScale Scaling enum Control external scaling
internalDisplayScale Scaling enum Control internal display scaling
Note:
  • Custom resolution must be supported by the monitor.
  • Incorrect resolution may result in display issues.
  • Best practice: test in a small OU before large rollout.
  • If scaling and resolution conflict, ChromeOS may prioritize supported values.

Chrome OS Disabled Device Return Instructions Template

This policy allows administrators to display a custom message on ChromeOS devices that have been disabled (for example, lost, stolen, or deprovisioned devices).

The message appears on the device screen when it is in a disabled state.

Field What to Replace Effect
{{ORGUNIT}} OU ID Applies policy to that OU
"Please return it." Custom recovery message Displays message when device is disabled
Note:
  • This message appears only when the device is disabled.
  • It does not appear during normal operation.
  • Keep the message clear and concise.
  • Include contact information for best results.
  • Test on a small OU before mass deployment.
